The solenoid stop valve Q23JD-L20 is widely used in the industrial field, and its control method is crucial to the stable operation of the equipment. Understanding its control method can help users better play the role of the solenoid valve and ensure the normal operation of the system.

1. Basic principles and structural foundations

The solenoid stop valve Q23JD-L20 is a two-position three-way stop solenoid valve made of aluminum alloy, with a threaded connection, suitable for air media, and its main purpose is to achieve a reversing function. Its working process involves multiple components. The controlled medium enters the valve through the air inlet and must flow through the throttle hole before flowing out of the outlet. The throttle hole is controlled to open and close by the plunger. The normally closed Q23JD-L20 uses the plunger head of the throttle hole to press the spring, relying on the sealing material at the front end of the plunger head to prevent the medium from entering until the plunger is lifted by the electromagnetic field generated by the coil, thereby realizing the opening of the valve.

2. Electrical control method

Voltage type: Q23JD-L20 solenoid valve can use a variety of voltages, including AC220V, AC110V, AC36V and DC24V. Different application scenarios can choose the appropriate voltage type according to actual needs, which facilitates its adaptation in different electrical systems. For example, in some common industrial electrical environments, AC220V may be a more common choice; while in situations where safety requirements are high and low voltage control is required, DC24V may be more suitable.

Principle of electromagnetic control: The valve is controlled by controlling the current on and off of the electromagnet. When the coil is energized, an electromagnetic field is generated, which acts on the plunger, overcomes the pressure of the spring, lifts the plunger, opens the throttle hole, and allows the medium to pass; when the coil is de-energized, the electromagnetic field disappears, and the plunger resets under the action of the spring, closes the throttle hole, and prevents the medium from passing. This simple and efficient electromagnetic control method enables the solenoid valve to respond quickly to the control signal and achieve precise on-off control.

3. Combined control with other components

The solenoid stop valve Q23JD-L20 is usually used in combination with other components to achieve more complex and precise control. It can be combined with an electromagnetic pressure distribution valve, and controlled by the pressure air of the pressure distribution valve to achieve long-distance on-off control of the oil, gas, and water pipeline systems of the hydropower station. In industrial automation production lines, it may cooperate with various sensors and controllers to control the flow of gas in a certain logical order according to the requirements of the production process to achieve automatic operation of the equipment.

4. Control precautions

When using Q23JD-L20 for control, there are some precautions to pay attention to. First, before use, check whether the components are damaged during transportation to ensure that the components are normal during installation and use. During installation, it is necessary to pay attention to the direction of gas flow and whether the pipe connection is correct, otherwise it will affect the normal operation of the solenoid valve. During use, all requirements must be strictly observed, such as the working voltage must be within the specified range, the voltage fluctuation is allowed to be +10% ~ -15% of the rated value, and the parameters such as action frequency, working pressure and use temperature should be paid attention to. In addition, since dust may affect the performance of the solenoid valve, it is recommended to install a muffler or a muffler throttle valve at the exhaust port, and a filter should be installed in front of the valve to prevent metal particles, dust and oil in the pipe joints and pipes from entering the valve, affecting its normal control and service life. When installing, it should be installed according to the horizontal piping construction, avoiding vertical and inverted installation to ensure the stability and reliability of control.

The solenoid stop valve Q23JD-L20 plays an important role in different industrial scenarios through a variety of control methods. Correctly understanding and applying its control methods and paying attention to relevant control points can better utilize the solenoid valve, improve production efficiency, and ensure safe and stable operation of the system.
